APPARATUS FOR LEVELING COAL IN COKE-OVENS.

SPECIFICATION forming part of Letters Patent No. 639,570, dated December19, 1899.

Application filed March 7, 1893.

To all whom it may concern.-

Be it known that I, GUSTAV HILGENSTOOK, a subject of the King ofPrussia, German Emperor, residing at .Dahlhausen-on-the-Ruhr, Kingdom ofPrussia, Germany, have invented certain new and useful Improvements inApparatus for Leveling Coal in Coke-Ovens, of which the-following is afull and accurate specification, reference being had to the draw ings,forming a part thereof.

My invention relates to apparatus for leveling and consolidating thecoal dumped through the charging-chutes into the cokeovens and which,owing to the manner of charging the ovens, forms itself into conicalheaps. Heretofore this work has generally been accomplished by workmenoperating leveling-rakes; and the object of my invention is to provide asimple and efficient apparatus by which this work can be moreexpeditiously performed and with better results.

The nature of myimprovements will be best understood as described inconnection with the drawings, in which they are illustrated, and inwhich- Figure 1 is a side elevation showing my leveling device mounted,as it conveniently is, on the same truck with the coke-dischargingapparatus. Fig. 2 is a plan view of my machine. Fig. is a sideelevation, on a larger scale, of the portion of my apparatus which actsupon the coal. Fig. at is a plan view of the portion of the apparatusshown in Fig. 3. Fig. 5 is a sectional View taken through the top of thecoke-oven and through my leveling apparatus, the section being taken onthe line 5 5 of Fig. 4:. Fig. 6 is a sectional view of the levelingapparatus, taken as on the line 6 6 of Fig. 4:. Fig. 7 is a viewindicating a simple device by which a reengagement of parts may be madeat a certain stage in the operation of my device.

tindicates what I call the carrying-rod of my apparatus. It isconveniently made up, as shown, of two iron plates 75 i, (see Fig. 6,)secured together at top and to a bar 25 at bottom, said bar beingprovided on its under side with a rack, (indicated at z.) Thiscarrying-bar is supported in a horizontal position on bearings whichpermit it to move freely in the direction of its length. As shown, thesebearings consist of rolls M, which serve both to guide and support thebar.

61- d, &c., are grooved guide-rollers jour- 7o naled on pins (2, securedto the carrying-bar If and arranged, preferablyin pairs, as shown, so asto engage both the top and bottom of the shovel-carrying rods, which areindicated at a a. One of these rods a is supported on each side of thecarrying-bar '15, and to each of them is secured a series of clamps,(indicated atf which support the shovels, (indicated at f and f.) In thecase of the shov els fthe clamps f support directly-pivoted pins,(indicatcdat f,) upon which the shovelblades f are pivoted so as to turnupward freely in one direction, while their motion in the otherdirection is prevented by means of a stop-lug, such as projecting fromthe clamp f The other shovel-blades(indicated at f) are securelyfastened to the clamps and only move with them.

c 0 indicate pivot-pins secured to the bars a near their rear ends andto which are con- 0 nected the ends of connecting-rods s s, the otherends of which are pivotally connected with crank-pins extending out fromthe face of wheels or disks, as indicated at 70, and preferablyadjustable therein, as by means of 5 slots 70'. The wheels 70 arejournaled, as indicated, at or near the end of the carryingrod 2, and itwill be obvious that when the wheels is are rotated the rods a will bereciprocated in the bearing-rolls (Z.

.2 is a gear-wheel supported on the frame n and lying directly beneathand in position to engage with the bar 25 and its rack The gear-wheel 2is driven through the gearwheel .2 in turn actuated by the gear .2secured to the same axle with the gear-wheel .2 which is driven by agear .2, actuated by a crank driven from the motor on. The crank andwheel shaft has also connected to it, as shown in dotted lines, afriction-wheel, (indicated at h in Fig. 1,) which in turn drives asmaller gear-wheel h, the function of which is, when the parts are inthe position shown in Fig. 1, to come in contact with and drive thewheels 7t is; but these wheels may obviously be driven by hand or in anyother convenient manner.

g g indicate rollers journaled on a shaft g, which is supported at theend of the carrying-bar t on bracketed arms 9 15 Fig. 7, indicates arecess formed in the under side of the bar F, in which is situated apivot-pin 1), having depending from it a tooth p, which is free to moveupward and forward, but is prevented from moving backward by means of astop 19 19 indicates a lug or projection from the gear-wheel 2, whichwhen the parts are as shown in Fig. lwill come in contact with thepivoted tooth p as the gear-wheel revolves. As long as the gear-wheel isrevolving in a forward direction or to the right, as shown in Fig. 1,its lug 19 will simply raise the tooth p at each revolution. As soon asthe motion of the gear-wheel is reversed, however, it engages the toothp and forces the carryingbar t backward, so as to engage the gearwheel 2with the rack .2

In moving my apparatus around on the truck itis retracted to about theposition indicatedin dotted lines in Fig. 1, being brought to registerwith the open end of an oven which is being filled. The motor on is setin operation, so as to drive the gear-wheel z in a forward or right-handdirection. This gear being engaged with the rack .2, the carrying-hartis rapidly forced outward or forward into the oven until it reaches theposition indicated in Fig. 1. Just before reaching this position thegear-wheel 2 has left contact with the rack 21, and the carrying-barcomes to a stand still, with its wheels is in contact with thefriction-wheel h, which at once causes them to revolve and begins thework of reciprocating the shovel-carrying rods ct a. This causes theshovels fand f to move to and fro over the top of the 'fuel, pushingaway and leveling down the tops of the cones and bring ing the contentsof the oven to a dead-level. I have found it advantageous to make someof the shovels, as indicated atf stationary with regard to theirposition on the rods a, and those indicated atf movable on the pivotpinsf, but movable only in one direction, the stops f preventing them frommovingin the other direction. After the fuel in the oven is leveled offI reverse the motor, driving the gear-wheel a backward or toward theleft and reengaging it with the rack 2, either by theautomatically-acting device indicated in Fi 7 or any other convenientmechanism, or even by drawing the carryingbar backward by hand. Thecarrying-bar, with its attachments, is then readily withdrawn from theoven, the rollers passing down upon and compacting the fuel as they passover its top.

Having now described my invention, what I claim as new, and desire tosecure by Letters Patent, is-
